Technical Summary
CVE-2026-17156 is a vulnerability in IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.0 and 12.0.1.0 through 12.0.12.27 that enables a local attacker to execute arbitrary code due to insecure deserialization. The vulnerability is classified under CWE-502. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction required, and impacts to confidentiality, integrity, and availability rated high. No vendor advisory or patch information is provided in the input data.
Potential Impact
Successful exploitation of this vulnerability could allow a local attacker to execute arbitrary code on the affected system, potentially leading to full compromise of the application and underlying system. The impact includes complete loss of confidentiality, integrity, and availability of the affected software environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only and monitor for suspicious activity related to deserialization processes. Avoid executing untrusted serialized data where possible.
